Frontier Gas is a former (?) gas station chain. Chain O’ mines reused a scrapped sign to mark their mill. Under the paint you can barely make out: GLORY HOLE GOLD MILL.
The Calumet Elevator offices used to be flanked on both sides by rails. Now, only one side has engines running on it.
Pillsbury from across the Mississippi River and Stone Arch Bridge from the roof of the Washburn Crosby Elevator (aka Gold Medal Flour).

Canal Park (see bridge) and some of old downtown, formerly Duluth City Hall and Police Department (center-left). At least one star has appeared in the sky…

When it became “Hyde Park Hospital”, this portico was added onto the front.
This corner of the building was the coal room, used to feed the two big boilers inside. The steam equipment has been replaced with electric, so this section may not have changed much in the past decades.
Beside the shaft building are two fans on skids, indicating they were used underground.
